have you verified that these work?
All of them work, but some have a minimum payout threshold which you won't reach until you use the faucet several times... Thousands even, in the case of Bitcoin / Litecoin.
I just clicked it and I need to wait to get more quark as it says I not reached minimum payment yet so it will be interesting to see when I can get more and then request a cash out..

You can use this faucet as many times as you want, no need to wait

But I made some requests at 9 PM and still nothing in my wallet...
If you got a message saying you didn't reach the threshold payout amount, you won't receive anything. Use the faucet a few more times until you reach 0.001 (for Quark).
